Gas-Fired Dryers

CFW Projects’ energy-saving dryers and ovens can be provided with various heat sources. The use of gas as a fuel is growing fast because of its many advantages. In Southern Africa, recently discovered fields suggest that the availability and relative price of natural gas may improve greatly.

At CFW, we stay informed about the most cost-effective energy source to use for any particular drying application. We are able to advise clients at any stage of their business life cycle of what is likely to be the most profitable solution.

Gas is a thermally efficient and relatively clean fuel, burning as much as 40% cleaner than coal. The difference in sulphur emissions is particularly significant as the sulphur in many types of fuel can cause corrosion, reducing equipment life. Concerns around the handling and removal of ash are also eliminated, reducing downtime and maintenance.

It is often the preferred fuel for direct-fired dryers where it is acceptable for the product to come into direct contact with the combustion gases. In these cases, such dryers can be considerably more efficient than steam-heated systems. Direct drying also entails lower capital and maintenance costs. Applications in which direct-fired gas dryers are used include the drying of minerals, fishmeal, seeds and grains and various other products.

Gas-fired dryers are often more flexible as the heat load can be changed in a short time compared to alternative fuels, making it easier to produce a high-quality product. Even in cases where drying heat is usually generated by another means, gas can be used for co-generation so that load changes can be accomplished more smoothly and quickly.

Compared to wood and coal, gas can use relatively simple combustion equipment and has lower air supply requirements. Where the type of fuel used for a dryer or oven must be converted from oil, it is often possible to use a conversion burner rather than replacing the whole boiler or furnace, particularly early in the life of the equipment.

Where production is seasonal, gas can be more cost-effective than electricity, as monthly connection charges are avoided.
